Title: Improvements in laminates
Inventor: FRANIEL CAROL ANN
IPC: B29C65/00
Filed: 1969-07-21
Abstract: 1,244,893. Ceramic-fabric laminates. C. A. FRANIEL. 14 July, 1970 [21 July, 1969], No. 36575/69. Heading B5N. [Also in Division A4] A laminate comprises a ceramic layer having bonded to each surface thereof a layer of fabric impregnated with a silicone rubber. The ceramic layer may be coated on each face with an impact adhesive to which is bonded a fabric, e.g. woven fibreglass cloth, impregnated with the silicone rubber, e.g. by spraying, dipping or brushing, the solvents of which are evaporated. The laminate may be rolled and stapled or stitched by machining in a quilted pattern form. A plurality of the laminates may be laid one on top of another and bonded together in such a manner that the stitching or stapling in any laminate does not coincide with that of an adjacent laminate. The external faces of the laminate or assembly of laminates may have applied thereto additional components, e.g. aluminium foil, by plating metallization spraying or adhesion. The ceramic layer, which may contain fibres, may be in powder, paste or sheet form and may comprise china clay or other processed mineral ore, preferably containing aluminium silicate. The laminate may be used for cladding the interior or exterior surfaces of aircraft, vehicles, ships, buildings, machinery, instruments or kiosks, for packing cases or containers, for protective clothing, e.g. suits, aprons, headgear, gloves, and in the manufacture of waste disposal containers.

Title: Improvements in and relating to automatic vacuum braking apparatus
IPC: B60T13/46
Filed: 1933-12-29
Abstract: 424,228. Vacuum brakes. BROWN, D. F., and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Dec. 29, 1933, No. 36593. [Class 103 (i)] In automatic vacuum brake systems of the kind in which a supplementary reservoir is connected to the lower chamber of the brake cylinder to accelerate the release of the brakes, a cut-off valve is provided for preventing the reservoir from being exhausted when the vacuum in the train-pipe or lower cylinder chamber is below a relatively high value corresponding almost to complete release of the brakes. The cut-off valve device for the reservoir 1 comprises a non-return valve 13, the stem of which engages a diaphragm 17 subject on its upper side to a spring 20 and to the vacuum in the train-pipe 2 through passages 3<1>, 3 and non-return valve 4 and on its lower side to atmospheric pressure. The diaphragm 17 may instead be subject on its two sides to the vacuum in the upper and lower cylinder chambers. Thus unless the train-pipe vacuum is substantially at the normal release value the valve 13 is seated and prevents flow of air from the reservoir to the train-pipe which when the reservoir has equalized with the lower cylinder chamber would delay the further release of the brakes. The valve 13, however, permits flow of air at any time from the lower cylinder chamber to the reservoir under the control of a quick release valve device 6 such as described in Specification 424,500 and which comprises a diaphragm 8 subject in chambers 9, 10 respectively to the vacuum in the train-pipe 2 and lower cylinder chamber connected to pipe 5. The apparatus shown also includes a quickapplication device 21 comprising a diaphragm 24 subject to the vacuum conditions in chamber 25 connected to the train-pipe and in chamber 26 connected through passage 27 with a quickinshot valve device 22. The diaphragm 24 actuates a valve 23 which is normally seated to cut off the atmosphere from chamber 26. The device 22 comprises a diaphragm 31 subject on its two sides respectively to the vacuum conditions in the upper and lower cylinder chambers through passages 33, 5 and spring 35 and normally lifts a valve 30 to establish communication between chamber 26 and the lower cylinder chamber.

Abstract: 928,684. Focusing lens mount. COMPAGNIE FRANCAISE THOMSONHOUSTON. Oct. 29, 1959 [Oct. 29, 1958], No. 36760/59. Class 97 (1). [Also in Group XXIV] For focusing and varying the focal length of a television camera objective 2, a shaft 10 is rotatable about its axis and displaceable angularly about a constant velocity-ratio universal joint 10a. Rotation of the shaft 10 causes rotation of a toothed focusing ring 7 on the objective 2 by driving through the joint 10a a shaft 12 coupled by a belt or chain drive 16 to a shaft 17 having a pinion meshing the toothed ring 7. Angular displacement of the shaft 10 about the joint 10a in the plane of the figure causes a link 19 connected to the shaft by a fork joint 20 to rotate a lever 5 that moves the lenses 4 axially to alter the focal length of the objective 2.

Title: Improvements in or relating to hydraulic presses
IPC: B30B15/16
Filed: 1961-10-17
Abstract: 921,346. Hydraulic presses. SKAG STEUERUNGEN UND KUPPLUNGEN A.G. Oct. 17, 1961 [Oct. 17, 1960], No. 37270/61. Class 69 (2). A manually-operable control device for an hydraulic press comprises a piston 12, a control shaft 27 having an actuating member for regulating the piston pressure, a rotary slide valve 14 for controlling the direction of movement of the piston, and a connection between the valve and control shaft consisting of a driving disc 32 and actuating disc 33 having coacting means 34, 35 whereby rotation of the control shaft moves the valve through substantially one-quarter of a revolution, and ratchet means 36, 37 for locking the valve during further rotation of the control shaft. The control shaft is supported in the wall 16 of a reservoir 20 and in a bore 28 in a valve housing 13 between an electrically-driven pump 15 and the piston 12 and cylinder 11 of the press. The valve 14 is disposed between passages 17, 19 leading to the pump and reservoir and controls the supply to one or other of a pair of pipes leading to opposite ends of the cylinder. A passage 38 leads from the passage 17 to the bore 28 and an exhaust passage 39 connected to the reservoir, and the end of the shaft 27 has a portion shaped so that rotation of the shaft varies the flow to the reservoir and the pressure of the fluid supplied to the piston. During initial rotation from a neutral position of the shaft 27 by a handle 31, a peg 34 on the driving disc 32 engages a slot 35 in the actuating disc 33 to rotate the valve through a quarter of a turn from its neutral position to a position connecting the supply passage 17 to one or other of the passages leading to the ends of the cylinder, the shaped portion in the shaft 27 maintaining the passage 39 open so that only a minimum pressure is applied to the piston. On further rotation of the control-shaft, the shaped portion on the shaft restricts the flow to the exhaust passage to raise the pressure of fluid supplied to the piston. During the further rotation of the shaft, the peg 34 leaves the slot but rotation of the valve is prevented by a cylindrical disc 36 on the shaft 27 engaging one or other of cut-out portions 37 in the actuating disc 33.

Title: Improvements relating to apparatus for regulating the flow of a fluid through a passage
Inventor: GALLO ELIA A
IPC: F02C9/16
Filed: 1955-12-30
Abstract: 806,345. Gas-turbine plant. CURTISSWRIGHT CORPORATION. Dec. 30, 1955, No. 37409/55. Class 110 (3). [Also in Group XXIX] Flow-regulating apparatus suitable for metering the supply of liquid fuel to an aircraft jet engine in response to the mass flow of air to the engine comprises a valve 18 controlling the flow of fuel from an inlet 15 to an outlet 16 and actuated by a flexible bellows 34 subject internally to a control pressure determined by the relative positioning of a nozzle 44 and a closure member 46 pivoted at 47, the interior of the bellows receiving liquid fuel under pressure through a restriction 40 and the nozzle 44 serving as a variable escape passage. The closure member 46 is acted upon by an adjustable spring 86, a spring 48 connected to a flowresponsive member 32 coacting with a seat 30, and a bellows 56 acting through a lever 58 pivoted at 66, a lever 74 pivoted at 76, and a pin 80 slidable in a bush 82. The bellows 56 may be partially evacuated or vented to atmosphere and is anchored at one end to a point 62 on an arm 64 whilst its other end is linked to the lever 58 whose pivot 56 is carried by the arm 64. The anchorage 72 of the arm 64 is adjustable manually or automatically in response to a particular operating condition to vary the transmission ratio between the bellows 56 and the lever 74. Flow of fuel past the valve member 32 results in the latter taking up a position dependent upon the rate of flow and thereby applying to the closure member 46 through the spring 48 a force which is proportional to the flow of fuel, whilst at the same time an opposing force dependent on the mass air flow is applied to the closure member through the pin 80. Thus any change in mass air flow is accompanied by an adjustment of the leakage through the nozzle 44 and a consequent adjustment of the valve 18 resulting in a change of fuel flow which gives rise to a variation in the force of the spring 48 to balance the force applied by the pin 80 due to the changed mass air flow. A pressure proportional to mass air flow is applied to the exterior of the bellows 56 and may be, in the case of an aircraft jetengine, the impact pressure of the free air stream relative to the engine, this pressure being applied through a conduit 55. In a modification, suitable for a system employing a positive displacement fuel pump, the valve 18 is arranged as a by-pass valve instead of as a throttle valve.

The driven pin 9, Fig. 9, of the eccentric is adjustable by a screw 9G, 9H and drives link 8 which is pivoted at 8A, Fig. 1, to link 7C. This is pivoted to the frame 1 of the apparatus at 7E and to link 6, through a ball universal joint 7. A ball joint 5 on the other end of link 6, which may be varied in length by different central sections 6C, connects the link to the operating lever 4, Fig. 4, of the gripper 3, which may have a knurled work-engaging face. A spring 4F urges the gripper towards the work, and a screw 4C provides adjustment for different strip thicknesses. Friction between the slide 2A and slideway 2 is increased by springs 2H acting between the slide and its dovetailed jib 2E. A blade 14A, Fig. 2, on an eccentric pivot 14B in a stationary clamp 14C prevents movement of the strip during return movements of the gripper 3 and can be withdrawn by turning a pin 15C between stops 14D, thus rotating eccentric 14B. A spring-pressed pin 14G biases the blade 14A towards the strip. Specifications 666,170, 718,042 and 738,416 are referred to.
